吸入マニホールド装置。[Claims for Utility Model Registration] (1) On one side of the engine body E, there are a plurality of air-fuel mixture passages (4, 4...) communicating with the plurality of intake ports (Ip, Ip...) of the engine body E. In a water-cooled engine joined to an intake manifold Mi having a mixture distribution chamber 3 that branches these, the engine body E is provided with an exhaust recirculation port Rp branching from the outermost exhaust port Ep of the engine body E, and The exhaust gas recirculation port Rp is opened at the joint surface of the engine main body E with the intake manifold Mi, and one end of the exhaust gas recirculation port Rp directly communicates with the opening of the exhaust gas recirculation port Rp, and the other end of the exhaust gas is opened to the mixture distribution chamber 3. A recirculation passage 6 is formed integrally with the wall 5 of the intake manifold Mi along the outermost air-fuel mixture passage 4, and a flow control valve 9 interposed in the middle of the exhaust gas recirculation passage 6 is connected to the intake manifold. A water-cooled engine, the water-cooled engine having a flow path 14 disposed on the outer side of the engine Mi, and further having a flow path 14 formed in the wall 5 adjacent to the exhaust gas recirculation path 6 at least upstream of the flow rate control valve 9 and communicating with the engine cooling water channel. suction manifold device. (2) The air-fuel mixture distribution chamber 3 is provided with the exhaust gas recirculation path 6.
An intake manifold device for a water-cooled engine according to claim (1) of the registered utility model, which is provided with a baffle plate 7 facing an opening 6a. (3) The intake manifold device for a water-cooled engine according to claim 1, wherein the flow path 14 extends from the hot water riser chamber 10 that heats the air-fuel mixture distribution chamber 3.
